[Techtoolslist] Crystal Castles ROM Address Range

[Danny Pearson]

Hi Justin, I wrote a script for the 9010 for Return of the Jedi which does the same thing.  It bank switches between 3 pages at the same memory location.    Source is at: 
ftp://ttl.arcadetech.org/TTL/Test_Equipment/Fluke/9010%20scripts/Jedi.9lc
See the areas for rom3/4/5 to see what I did, I think the MAME source had the information on what to write and where to get the page to switch.
